Floyd Mayweather to fight Don Moore in front of just 20 VIP fans with tickets costing £150k and only available as NFTs

Mayweather, 45, who claimed he was paid £1m just to attend the press conference of his return, retired professionally in 2017.

But even after beating UFC superstar Conor McGregor, 33, he has boxed twice since.

Both were in exhibitions against kickboxer Tenshin Nasukawa, 23, and YouTuber Logan Paul, 27, as recently as June.

Mayweather's spectacle bout with Paul - who weighed TWO STONE more - ended without a winner after no knockout was scored.

Now he prepares to step foot in the ring once more and will do so against Moore, 42, who he began sparring with in 2012.

Mayweather told : "I was able to leave boxing on my own terms and now the boxing critics are upset that I am still able to milk and finesse the sport of boxing by throwing exhibitions.

"Sixteen minutes and I am able to get eight and nine figures from the fruits of my labour.

"Once again I am not hurting for my money, I am far from hurting for money. I didn't retire from getting money."
